Used for heating, ventilation and air conditioning. The actuators serve to control the room temperature and can be used e.g. with conventional radiators, radiators with integrated distributor, distributors/collectors for surface heating, radiant ceiling panels, chilled ceiling systems and induction air systems.

The actuators (0 - 10 V) can be used in centralised building control systems in combination with the electronic room thermostat, item no. 1152151, or with a central controller.

The reset function (NC: nomally closed) can be carried out mechanically or electrically. In case of electric reset function, the actuator returns to zero position with a stored residual energy within 30 seconds if the power supply is interrupted.
